Abstract :In this study, we aimed to determine the nematode diversity in soils from olive orchards in İzmir, Manisa, Çanakkale, and Balıkesir provinces. For this purpose, a survey was carried out in 2021-2022; in each orchard, soil samples were collected from 0-60 cm depth, and nematodes were extracted from collected soils by the modified Baermann Funnel method. Thirty-seven genera of nematodes insert ignore into journalissuearticles values(Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoides, Boleodorus, Cephalobus, Clarkus, Coslenchus, Ditylenchus, Dorylaimus, Eucephalobus, Filenchus, Geocenamus, Hemicriconemoides, Helicotylenchus, Labronema, Lelenchus, Longidorus, Mesocriconema, Mesodorylaimus, Mesorhabditis, Monhystera, Panagrolaimus, Paratylenchus, Pratylenchus, Pratylenchoides, Psilenchus, Rhabditis, Rotylenchulus, Rotylenchus, Saurtylenchus, Tripyla, Tylenchorhynchus, Tylenchus, Xiphinema); from 21 families were identified in olive-growing areas. According to feeding habitats, nematodes were classified as plant parasitic insert ignore into journalissuearticles values(19 genera and one plant-parasitic species from fungivore Ditylenchus genera);, bacterivores insert ignore into journalissuearticles values(11 genera);, fungivores insert ignore into journalissuearticles values(3 genera);, omnivores insert ignore into journalissuearticles values(2 genera);, and predators insert ignore into journalissuearticles values(2 genera);. Plant-parasitic 27 nematode species insert ignore into journalissuearticles values(İzmir: 19; Manisa: 16; Balıkesir 15; Çanakkale: 11); were found in soils. The virus vector Longidorus elongatus was among the identified important species. The prevalent plant-parasitic species were Geocenamus brevidens insert ignore into journalissuearticles values(32%);, Filenchus thornei insert ignore into journalissuearticles values(23%);, Helicotylenchus digonicus insert ignore into journalissuearticles values(29%);, while the free-living nematodes were Acrobeloides spp. insert ignore into journalissuearticles values(100%);, Aphelenchus sp. insert ignore into journalissuearticles values(95.3 %);, Cephalobus spp. insert ignore into journalissuearticles values(97%);, and Mesodorylaimus insert ignore into journalissuearticles values(91.2%);. Within bacterivore nematodes, at least one species from the Cephalobidae family was determined in all soil samples.
